Well, the first pope knew nothing of cardinals, but today it is impossible as it is political like any other organization. But the Pope has to be a man, too. Goodness knows men are the spiritual ones by comparison...? :/
I love our new Pope:) But you need to be a priest who is promoted to different stages in his religious vocation with the last appointment as Cardinal..A Cardinal then can be appointed as The Pope by majority vote of the Cardinals.
